UNTTED STATES PATENT JOHN A. MOSHER, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE ADAMS WESTLAKE COMPANY, OF ILLINOIS.

ACETYLEN E-GS `G EN ERATOR.

SPECIFICATION forming part of Letters Patent No. 674,611, dated. May 21, 1901.

Application led August 22, 1900. Serial No. 27,680. (No model.)

To a/ZZ whom it may concern.-

Be it known that I, JOHN A. MOSHER, a' citizen of the United States of America, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Acetylene-Generators, of which the following is a specication, and which are illustrated in the accompanying drawings, forming a part thereof.

This invention relates to improvements in that type of acetylene-generators which forms the-subject of Letters Patent No. 652,974, granted to me July 3, 1900, its object being to provide means for preventing the escape of gas either from the generating-cell or the piping system when the cell is detached. This object is attained in the construction hereinafter described, and shown in the accompanying drawings, in which- Figure 1 is a detail elevation of the nipple of the generating-cell'and the nipple of the piping system. Fig. 2 is a detail side elevation of the same, partly in section. Fig. 3 is a detail rear elevation of the same, partly in section; and Fig. 4 is a detail of one of the valves.

The upper end of the generating-cell is shown at 10 and its neck or nipple at 11, the nipple of the piping system being shown at 12 and being supported by a wall-bracket 1,3.

At 14 is shown a valve crossing the neck 1l of the generating-cell, and at 15 the valve in the nipple 12, each valve being provided with a spring 16 17, by means of which it is automatically closed and each being provided with a crank-arm 18 19, by which it may be opened in opposition to the spring.

A link or clamping-bar 2O is provided with transverse recesses adjacent to its ends for the engagement of the crank-arms 1SA 19, so as to prevent the closure of the valves. This link or bar is secured to a cross-arm 21, form! ing a part of the bracket 13, by means of a thumb-screw 22,`and a spring 23 is set within a counterbore of the aperture in the bracketarm for receiving the screw and tends to throw the bar or link 20 away from the bracket when the screw is thrown back, so as to dis- While such a generating-cell is .usually provided with other means for holding it in engagement with the nipple of the piping system, it is obvious that it cannot be detached from this nipple while the crank-arm of its valve is held by the bar or link 20, and hence before the two nipples can be separated by turning back the screw 22 the valves must be released, so that they may automatically close, thereby preventing the escape of gas from either nipple when the partsare separated.

I claim as my invention- 1. In an acetylene-generator, a xed nipple having a spring-closed valve, a generatorcell adapted to detachably engage the nipple and having a spring-closed valve in its neck, and means for holding the valves open and securing the cell to the nipple.

2. In an acetylene-generator, in combination, a fixed nipple, a generator-cell adapted to engage the nipple and having a springclosed Valve, and a detent for engaging the valve-stem to hold the valve open and the cell in engagement with the nipple.

3. In an acetylene-generator, in combination, a fixed nipple having a spring-closed valve, a generating-cell adapted to detachably engage the nipple and having a springclosed valve, a crank-arm for each of such valves, a link for engaging such arms to hold the valves open when the cell is in engagement with the nipple, a bracket, and means for securing the link to the bracket.

4. In an acetylene-generator, in combination, a Xed nipple having a spring-closed valve, a generating-cell adapted to detachably engage the nipple and having a springclosed valve, a crank-arm for each of such valves, a bracket supporting the nipple, a bar having transverse recesses at its ends for engaging the crank-arms, and a screw for binding the bar to the bracket.
